To all whom it'may concern:

Be it known that I,'HENRY CLAY Mlonrn,"

Jr., a citizen of the United States, residing at Charlottesville, in the county of-Albemarle and State of Virginia, have invented new and useful Improvements in Hypodermic Syrin'ge.

Cases, of which the followingis a specification.

This invention relates to hypodermic-syringe cases, and has for its objects to produce a comparatively simple and inexpensive device of this character embodying means for sterilizing water in which the cover of 'the casing may be readily utilized as a container for the water to be heated, one wherein the heating lamp or stove will normallyoccupy an unobstructing position, and one wherein when the parts are in active position the cover will lie properly over the lamp.

Further objects of the invention are'to provide a device of this class in which the lampcasing will be normally locked in closed posi tion, one inwhich the heating device will when released be moved automatically to active position, and one wherein the outward movement of the lampwill be limited for properly positioning the same centrallybe neath the water-container.

invention comprises the novel features of construction and combination'of parts more fully hereinafter described.

In the accompanying drawings,'Figure 1 is a side elevation of a device embodying the invention and showing the parts in position for heating or sterilizing water. tional elevation, the section being taken centrally and longitudinally through the casing and the parts being shown innormal-position. Fig. 3 is a section taken on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of the lamp and its casing. Fig. 5 is asection taken on the line 5 5 of Fig. 2 as viewed in :the direction of the arrow.

Referring to the drawings, 1. designates the syringe-case, provided with a cover 2, hinged at 3 to the case and normally maintained in closed position by means of a spring-catch 4, there being arranged within the case a syringe 5, a plurality of tubes 6, and a needle 7.

The foregoing parts, except as hereinafter explained, may all be of the usual construction and arrangement and fada'pted to per-' form their ordinary functions.

In accordance with myinvention the case 1 has positioned therein at a point above and suitablyremote from its bottom '8 a partition 9, which jointly with the bottom produces a chamber or compartment 10, adapted to communicate at its outer end with the lower" end of-a compartment'or'recess 11,'formed in:

and extending longitudinallyof the case the" compartment 111 being'de'signed to open'toward that side" of the case'to which the cover" 2 is'hinged, while the coveri2 is sha-ped,'as-

herein shown, to present a container-the bot tom of which inclines downward to a central 1 point 12 for a purpose whichwillpresently appear. Arranged and normally" housed within 'the compartment' 10 is a box-casing 13, provided at its outer" endwith a sliding door or cover 14 and-adapted to receive 'a' bottle or other-liquid-holding vessel 15, there beinggfixed on'the upperwallbf the casing and at the outer'end'ofthelattera heating device or lamp '16," which is normally housedin the recess orcompartment' 1 1 and inclosed therein by means of a section :or'pla'te 1?, at taohed to and movable with the box 13. The lamp 16 is equipped with a wick 18 anda burner 19, on which isseated a cap 20.

Disposed in the compartment 10- and: in' rear of'the box 13 is a normally compressed coiled I spring 2 1 preferably elliptical form in cross-section, while provided on the inner end of-the casing'13 is a lip 01'' projection =22'," adaptedto be normally engaged by the head 23 or a spring-latch 24, whereby the casing ismaintained in normal position with the spring 21 compressed, itbeing noted thatwhen'thelatch is manipulated for releasing the casing the 'latter'will, through expansionof spring: 21, be moved automatically to active -position, as seen in Fig. 1, and in which position of theparts the-lip 22 will contact with a stop or abutment25, provided at the'forwardend of "the compartment '10 to limit the outward movement'of the casing;

By preference the latch 24' is carried at thelower end of a spring-arm 26*, attached at its upper end to the case 1 and equipped with a push-button 27, projecting through a suitable opening in the adjacent wall of the casing, there being formed in the partition 9 an opening 28, through which the head 23 projects for engagement with the lip 22, attention being directed in this connection to the fact that the outer end of the head 23 is beveied or inclined and will when the button 27 is pushed inward ride upward on the adjacent edge wall of the opening 28 for positive movement to releasing position.

In the arrangement of parts within the case 1 the needle or needles 7 are positioned directly above the compartment 11, while the syringe 5 is disposed, as usual, at the center of the case, with the tubes 6 disposed on opposite sides of the syringe, it being apparent from this arrangement that all of the space within the case is utilized and is so econornized as to obviate increasing the usual dimensions of the case for the accommodation of the heating apparatus other than by a slight increase in the length of the case to provide the compartment for receiving the OX or casmg 13.

In practice when it is desired to boil or sterilize water or other liquid for use in the syringe 5 the cover 2 is swung open to the position illustrated in Fig. 1 and the latch 24 operated to release the casing 13, whereupon the spring 21 will move the heating device 16 automatically to position beneath the cover, it being noted that theoutward movement of the heater is limited, as heretofore explained, thus insuring the lamp being positioned directly and centrally beneath the point 12 of the cover, which latter is provided with a stop or lug 29, designed to contact with the wall of the case for limiting opening movement of the cover when the same arrives at true horizontal position. The slide 14 is next opened to permit removal of the bottle 15, which carries a supply of water, it being apparent that this water may be quickly boiled in the cover 2 by the action of heatfrom the lamp 16. It is to be noted in this connection that owing to the peculiar formation of the cover the smallest quantity of water contained therein will in seeking its level lie di rectly above the flame of the lamp, thus to be uickly and effectually heated. It is to be 0 served that under this construction provision is made for readily and conveniently sterilizing water for use in the syringe and that the latter may while heating the water be at thesame time boiled and sterilized preparatory for use. i

From the foregoin it is apparent that I have provided a simp e device which in practice will admirably perform its functions to the attainment withthe ends in view, it be ing understood that minor changes in the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the class described a case provided with a cover and a heating device normally housed in the case and designed to be positioned for heating a liquid contained in the cover when in open position.

2. In a device of the class described a case provided with a cover adapted for movement to open position, a heating device normally housed in the case and means for moving the device to a position beneath the cover when in open position.

3. In a device of the class described a case, a cover connected therewith and adapted for movement to open position, a heating device normally housed in the case, means for automatically moving the device to a position beneath the cover when in open position and means for limiting the movement of the device.

4. In a device of the class described a case provided with a movable cover constituting a container, the bottom of the latter being depressed at its center, a heating device normally housed in the casing and movable to a position beneath the container and means for limiting the movement of the device whereby the latter will be positioned centrally beneath the depressed bottom of the container.

5. In a device of the class described a case provided with a movable cover constituting a container, a heater normally housed in the case, a spring for automatically moving the heater to a position beneath the container and means for limiting the outward movement of the heater.

6. In a device of the class described a case provided with a movable cover constituting a container, said case having a compartment, a heater normally housed in the compartment and movable 'to active position beneath the container, a spring for automatically movin the heater to active osition, means for limlting such movement 0 the heater and means for locking the latter in normal position within the casing.

In testimony whereof I afiix my signature in presence of two witnesses.
